Shared Text for Split i/d
From: dave at UCLA-Security (David Butterfield)
The 411 files ARE shared. Sharing is accomplished in text.c
where it attempts to "attach to a shared text segment". It
knows that it is shared by looking at the text size and seeing
that it is non-zero. This size is read directly out of the
header on the a.out file (printed by the "size" program). The
exception is that at exec time (getxfile in sys1.c), a file
which is 407 (non shared, non-sep) has its text size set to
zero and its data size set to the sum of the original text
and data sizes. This 411 files are shared.
